These elements will purify a minimum of 6000 gallons before needed to be replaced.

PH (alkalinity) of the water

The Berkey filters increase the PH (alkalinity) of the water. Pathogenic bacteria and viruses have difficulty surviving in alkaline environments so this helpful in keeping your water pure. It also helps to lower the number bacteria and viruses in your body when you drink Berkey water for the same reason.

Minerals

Black Berkey elements are built to leave the beneficial minerals in the water and to remove only the unwanted heavy metals like lead and mercury and sedimentary minerals like iron oxide and aluminum.

Maintenance

As you use the filters and they start to drip more slowly, it is because turbidity and sediment are clogging the micro-pores of the purification elements. Just remove the elements from your system, scrub the outside of both elements with preferably a ScotchBrite pad, stiff toothbrush, or vegetable brush. Scrub a section of the filter until you see a little black on the pad and then move to the next part of it. It’s simple to do and takes only a few minutes.

What if you are never required to rely on the Berkey's unique ability to draw water from contaminated, untreated sources of drinking water. Chances are you could go your whole life and avoid this situation. What if we could depend on others to ensure that the water you and your family drinks is free of harmful contaminants. What if all of the water you consumed was healthy and free from additives others thought were necessary for your well being. What if all water tasted great and was free of foul odors associated with chemicals like chlorine.

Berkey water filter systems are so versatile that for pennies a day you will not have to worry about any of these water filtering problems. Simply pour water into the unit and minutes later you will be rewarded with purified drinking water.

Each water filtering system comes with filters that will last a minimum of 6000 gallons. That means years of great tasting, chemical free purified drinking water without ever having the expense of replacing the filter elements.

Imagine the relief and piece of mind of having a purification method that allowed you to utilize water sources redily available to you like, lakes, ponds, streams, rivers and swimming pools all without having the need for water pressure or electricity.
